Hi! Is there any way to put into Quickbooks a CSV file with a list of sales invoices and purchases from another system? Something like the banking tool but for invoices?

Hello David

Welcome to the Community.You can import invoices or bills from a CSV directly into QuickBooks Online.To do this go to the cog in the top right>import data>invoices(for example) then browse to the CSV(there is a sample that shows what columns are needed which you can look at) and then upload it.You can then do the same process for bills it is just a case of creating a separate CSV.
